DYNAMICS-15 A block with a spring attached to one end slides along a rough surface with an initial velocity of 7 m/s. After it slides 4 m, it impacts a wall for 0.1 s, and then slides 10 m in the opposite direction before coming to a stop. If the block's deceleration is assumed constant and the contraction of the spring is negligible, what is the average acceleration of the block during impact with the wall? spring block +X (A)...

A block of ice slides along a frictionless horizontal track with a speed of 1.2 m/s. At the end of the track is a horizontally mounted spring. The ice block slides along the track until it makes contact with the spring causing it to compress. What is the speed of the ice block when the spring has been compressed by 60% of the maximum compression length?
